BEVERLEY residing` at Coventry, Englandyhave invented certain new anduseful Improvements: in@ Infolding-Machines, of which kthe following fisa specication,

- In machines for lfolding collar. cufl"` `and like blanks, itisfrequentlyjdesired togalter -thefsequencefin whicli'the edges arefolded, ,r i thus, it is sometimesdesired to fold the sides first, andthe ends last,orI it may be desired.

' to fold one or other of the sidesfrst then l vfoldf the-ends` andthengfold the other side.` to 'get rvarious forms The *purpose of thisis of lock corners.

y Accordingto the present invention the op?, erating membersfor the sideand end folders f are all adjustable andthe-adjusting mechanism 1 isoperatedzyfrom4 a5' common'- member which may-ehe moved into 'variousset vposi-v tions to adjust one or more of `thebperati'ng members andleave `the others undisturbed.

able foldersc, which are mounted in carriers b and the presser platewhich is guided and -lsupportedfin the frame a. The folders` yc, areshown in Fig.' 6, moved into their fold-- ing position, this bythecentrally pivoted levers 7, carrying at movement being effected theirlower ends rollers g, which engagewith cams 54 54 and v56,56to move thefolders at the desired timesuand in the desiredse` quenceV as described@more fully hereafter The present invention is more specifically tionofthe folders sothat they may be moved 1n' vvariable sequence.

struction ofythismovable and adjustable die d. l l head ismorefullyvdescribed in aco-pending l `15,thereis pivoted at 14, a rod-12.About `midwayiirthe length of the-rod 12, thereis mounted a roller l1,which is guided inal curved slot 10, on a fixed bracket `9. The upperend of the-lever 12, is expanded to form a bearing for the' swivel 13,for the die head it' L' By from the Vposition shownin Fig." l, tothatshowny inFig. 6. This is effected by the' i means of` a .pin 7, carried.by the die head 7L i, the die headis swung aroundy pin 7, traveling inthe'curved groove 8',

formed onthey upper part` o f the bracket 9. The die-head z, z,'.passesoverftwo end col-i `umns @,farranged atfe'achxlside of the ma?L ichine. These l end columns 'are i supported in `an 'inclinedposltionlina fixed; sleeve Q ,and

carry at their lower ends (see Figs. l, and 3) arms 3, on which'areinounteclrollerfs'4. `The f roller 4, engages with the face came, torotate thestandards e, at required times.` v,The

rotation of the standards a, causes the die head parts/zzf, to cometogether or expand for the purpose which i is more fullyfex-` plainedhereafter;y Below the y folders c, o

Fig. 6, thereis mounted a hot presser. plate d, this presser plate restsonsprings n, and has panded position shown in Figs. vl andl 6.; Thefolders c, arethen drawn apart farl enough to 'freely admit theexpanded: dies e.' The dies e, press the blank A on to thel jthelfolders c. Immediatelythe yolies e, pass'y 'I a pin c, proj 'e'ctingdownwardly tore'st" on :an

arm pivoted at 79, and carrying a roller Z. r)lie roller Z, rest-s on acam m.

shown in Fig. l, along the pathshown by the dotted line Y on,tothe'guides or col umns e. The dies e, are then in the exe hotpresserplate d, and'thereby pass below below the folders c,theseffolders are moved into the positions shown in Fig. 6, inra defi`nite sequence which maybe ifaried asre` uired. From this position untilthel roller g l ,starts to rise at the point ILthe die heads l. lz', 7L,are brought 'together bythe rotation of the columns e, and the die headsalsostart to move upwardly Vfrom the table. In order to prevent themovement of thedies e, from scraping orv disturbing the blank A, ay pin:2 0 (sec F igs. l and 3) carried by thedief head comes to bear on aspring 21a contained in a recess 21. This happens when the die v head is'moving into its lowermost position' solthat the weight of the die headdoes not i fall on the blank, but` is taken up byl the spring 21'. Whenthe point II passes un- I der'th'e roller Z, the hot pressertable cZ, is

moved upwardly to press the blank. From the. points II to IH, the blankis pressed and at the pointIII, the presser plate eZ, re l. ced'es ashortdistance for the blank wheres upon the folders c, are withdrawnurlAtthe point IV, the presser plate (Z, gets a rapid idrop whereby thefolded blank falls fromv the table. y x

Having described the general operation of the machine, l .shall nowproceed to deal with the novel features according to this" inj vention.Thesenovel features referto the timing mechanism of the side foldersc c,

and the end folders-22.

Referring to Fig. 5, it willbe seen thatv the blank A, shownas-.a-vcollar blank, has to f be'ffolded along the vfour edges,A,A%y A3,

At'. If various .kinds of lock corners are desired, the ledges have tobefolded in a' dif-V ferent sequence, for instance, the side A- may befolded iirst,whereupon the 4ends A3, A4, may beffolded and then thexsideA2,'v may Abe'folded.` The operation might beE reversed that is to say,the sideA2, might be folded first, 'and 'then the ends Asa-nd A4,]

and lastly -the side A". A third alternative "l would betofold the sidesA and A2 simultaneously and first, and theendsv A3 and A4,!

f ,effect one orothe'r offrthesequences described last,- or 5a fourth'lalternative ispo'ssible movement.

A and A2, simulta neously` and last. According to the present invention,means are. provided lfor securing any one of these alternative methodsmerely by operating a singlesetting member and this in spite fof. thefact thattheside folders c, and the end folders 22, move in transversepaths. l

"The sets ofoperating cams 54, 54 and 56, 56 for the side folders are inpairs and `are. all mounted on a common shaft '8, The pair vof cams 54,`54 are the early and late cams respectively for the lower folderontheleft ,hand sidein Fig. 6, that is to the front of the operating shaft s,while the cams 56, 56 are the early and late cams for the upper folderon the'right hand side in Fig.` 6, that is tothe rear of vthe operatingshaft s. The

dles 56, whichfare onop'posite sides ofthe folding the ends'A3 andAffrs'tand the sides i rollers Q, are Vslidab'ly mounted on theirspinilf.

shaft s, so asto :nove the folders c, toward A andl away from oneanother. Each slidable f roller isthus located to 'co-actfwith `.eithercam of one pair o'r set. As seen Figs. 3 and 4, the rollers gk aregrooved, so asto leave two pr'ojectingpa-rts between which a Vshiftingrod may engage, F The roller g, for the rleft hand side yfolderin Fig.6, is formed of twofrol-ler parts 53,betweenwhich engages ani" operatingbar 5l, which is adaptedto slide the roller g-along its 'spindle 56a, so

asto bring one or other ofthe roller parts `53 into-'engagement withthecam 54 `or 54?.

The vroller g for, the righf'hand-` side folder' in Fig. 6 is'composed`of-'two rollers 5 5, and

forked and thefree space between the armsin a similar manner is causedbytheoperat-V ing bar 52 to slidealong its "spindle 56a, to bring oneorthe Otherb-ftheroller parts 55 vinto' engagement: withthe `cam 56 01H56.
